It was supposed to be a simple mission. All I had to do was collect some samples from a contaminated area under the sea. As soon as I left the ship, everything went wrong.

All I can do is move forward with this operations drone as my only companion. Trouble is, it's been acting sort of weird lately. Almost as if it's trying to sabotage my mission…
